To all whom it may concern: Beit known that I, ALBERT a citizen of the United States', residing H. STBBINS,

Los Angeles, in the county of Los An eles and State of California, have invente Improvement in Conveyers, of which the following description, in connection with the accompanying drawings, isa specification, like characters onthe drawings representing like parts.

This invention relates to conveyers, and more particularly to a conveyer Vconstruct1on for conducting materials 1n al horizontal direction.

VThe primary object "of the present invention 1s to provide a conveyer which is sim ple in constructie-mand may bereadily stalled and operated t'o convey materials in a horizontal direction from one place abther. 4

@ne important feature of the :present vention resides in ymeans for supporting and operatlng a,4 trough r other material sup'- porting surface to `p'ronrote travel of ma-y terials along the same.

A more specific eatureof'the invention resides in an unbalanced yWheel which serves to impart a back and forth movement the trough brother material supporting surface.

Other features of the invention and novel In the drawin z Fig. 1 is a si e elevation of a conveyor constructed in accordance with the present invention: and j Fig@ is an enlarged perspectlve view parts showninFig. 1.

In ,the embodiment. of the invention illustrated, a trough 10 is shown which o lis adapted to receive the materials to be conveyed `-and to direct. the materials lon'- tu'dinally thereof. The trough 10,:niayY variously constructedgand in the construe tion shown. is; tanned :ofimetal hevm 'La bottom 11 and upstanding 'si-des 12J Vcomprise ms having "the j 1ste. seria r. sinken. eenige may e@ sa -up fer @Emerg up any avai able spatie,i 'and -'n the present case shown as suspended from tleceiliig l?, of: a building, and the ceiling, is "lsec'ed 4to 1100i` beams 14 which Suppen the 116er 15.

The trough 10 "may,V vbe varidisly 55 ported to receive movement that will eject travel of materiale ldnfgftuuhally thereof, and in the `presein commissie@ ihetratg is suspended in ahorizontal-'bstioi from me eenling i3, by arme 16. i `Heymans may V U-siafid' con; struct-,ibn shown, 'and 'may Have an itere dia-te portion 17 niet, 'efterfdsvner the trough i0; and laterally exix-errlinggeen` @te tiene 1e that enfermeria apertures in brackets v19fsia 1il-e 1 to the oei ing. The por tion 17 `or the tro'gh sup crti'ng farms; pref; erab'lyis jonrnald in a earni'gfbraoket e0 secured tf thaurider face of thetro 1L-and the upperends 18 'of the su-'lpoift'n' r4 frrfis are journaled in the brackets 19 for swing; ing movement. v j; i

A hpper 2'1 may serve to deliver the naterials to be cnveyed vto V'the trough from the Hoor above, .and the trough mayA be variously operated to cause the materials to travel alongthe saine. Inlthe riesentcliS'e it yis assumed that the materias are to be conveyed alon the trough in the direction indicated by Lglie arrow,- Vand I'this ma be accomplished by impartingF a Back and orth movement to the trough which will ciise the trough to be., raised by the arms 16y as it moves in th'e directionin which the materials are to travel, and 4vvill be lowered bythe arms "as the troughwmoves v,in the opposite direction. In other Avvods the `trough should be operated so that an up,-

throjw will beiipartedthreto asit 4moves in the ydireciieri, in which .the meteifw "0 travel. This uptlirow movement ,willmcuse the.v mLUBIHlSO, tossed a.L0 i the troigh geheimer. ce; noemen taugt is arrested, in theY ujathroiaetlitititi,onE 'l'.yhe mevementmsiith trou h Q in theopposite drectqn. yPtafereel-ys ou; d... be. .fore th, .lfirewlithefyeitiealrvestien so that the materials Wil-l be force toward the bottom of the trough by their momentum rather than lengthwise of the trough as the trough is brought to rest in this direction.

Various means may be provided for imparting back and forth movement to the trough 10 and simple means to this end consista., in operating the ,trough .from an unbalaiiced Wheel' so that the"'mover'r'ie'nt which results from rotating an unbalanced wheel will be imparted to the trough. In the present case a shaft 22- is journaled in bearings 23 secured to the trough 10, and an unbalanced wheel 24 is mounted upon the shaft 22 upon each.. side.. of the trough. The shaft and unbalanced wheels may be rotated from a pulley 25 driven,- by a belt 26. A weight 27 secured to one side of the Wheelsi24 serves tothrovv them out of balance and as the Wheels 24 are rotated they willimpart a back and forth movement to the trough 'which supports them.

.'Iirave of materialsalong the, trough may beiA further `promoted@by providing bump means to arrest the trough: suddenlyfwhile moving. in, the direction -Indicated by the arrowand to this end,.a beam 28;.iss'ecured to thej lower face of the tr-oughftransversely thereof I in position; Ato strike against fixed bracket-s ;29 secured to the ceiling 13 and.

I

From the'foregoingdescri tion and drawings it'l will bei seen that t e present conveyer `is extremelyvsimple. in 'construction :mdf-operation', and since vthe unbalanced wheels Whichfoperate the trough are supported thereby, the trough operating means does not need to be supported independently of the trough, and as a result the conveyer may bereadily installed for operation. --What is claimed is:

1. A conveyer comprising in combination, avtrou'gh supportedin a horizontal position l 'formo'VemeI-it' back and Vforth in :the directibn-of its `lengftlnand Ian'y unbalanced Wheel operableto i1npart'-.-the movement resultin fromI fitsffunbalanoed frotation tothe -trougwformovementbf the trough backand forth 'trouglillengthwise thereof.

4. A conveyor comprising in combination, a trough supported by swinging arms for movement back and forth in the direction of its length and having the arms arranged to impart an upthrow movement to the trough as the 'latter moves in one direction to facilitate travel of materials along the trough, and an unbalanced wheel rotatably supported by the trough to impart the movement resulting from its unbalanced-rotation to the trough to move the latter back and forth.v

5. A. conveyer comprising in combination, ay conveying surface supported in a horizontal position by swinging arms for movement back andforth inthe direction of its length, and an unbalanced wheel connected to the con-veying'surfaceeand operable upon rotation to move thesurfaceback and forth with `1 bumping efect theneby to promote travel of materials along said surface.

-6. A? -conve-yer comprising in combination, a trou` h for conducting materials len hwise t ereof,'.` andl an unbalanced w eel mounted upon lthe trough to vibrate the latterE upon rotation of the Wheel and thereby promote'travel of -materials along the trough.

7. A conveyor comprising in combination, awtrough lforiconducting materials lengthwise thereof, means for supporting the trough for movement back and forth in the direction of its len th, and trough operating means supported entirely by the trough Vand operable to move the trough back and forth to promote travel of materials along the trough.

8. A conveyer comprising in combination,

means carried hy 'the trough and adapted upon rotation to shake the trough and impart a back and forth movement thereto.

10. A conveyer comprising in combination, a conveying surface supported in suhstantially a horizontal position for back and forth movement in the direction of its length, unbalanced rotatable means adapted to vibrate upon rotation, and means for imparting the vbratory movement of the un- 10 balanced means to the Conveying surface to move the latter back and forth.

In testimony whereof, I have signed my name to this specification.
